WCF 通过 HTTP GET

Question

我有一个 WCF 服务，我正试图通过浏览器访问它。它可以通过测试客户端正常工作，但是使用浏览器时不会调用我的断点[点。我的 web.config 有

<system.serviceModel>
    <client>
        <endpoint address="http://localhost:84/BillService.svc"
            binding="webHttpBindingConfig" bindingConfiguration="BasicHttpBinding_IBillService"
            behaviorConfiguration="json"
            contract="iBillService.IBillService" name="BasicHttpBinding_IBillService" />
    </client>
    <behaviors>
        <serviceBehaviors>
            <behavior name="">
                <serviceMetadata httpGetEnabled="true" />
                <serviceDebug includeExceptionDetailInFaults="true" />
            </behavior>
            <behavior name="Behavior">
              <serviceMetadata httpGetEnabled="true" />
              <serviceDebug includeExceptionDetailInFaults="true" />
            </behavior>
        </serviceBehaviors>
        <endpointBehaviors>
          <behavior name="json">
            <webHttp/>
          </behavior>
        </endpointBehaviors>
    </behaviors>

    <!-- turn off authentication in WCF, we get the client from the HttpContext -->
    <bindings>
        <basicHttpBinding>
            <binding name="CustomBasicAuth">
                <security mode="None">
                    <transport clientCredentialType="None" />
                </security>
            </binding>
            <binding name="BasicHttpBinding_IBillService" closeTimeout="00:01:00"
                openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"

                useDefaultWebProxy="true">
                <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
                    maxBytesPerRead="4096" maxNameTableCharCount="16384" />
                <security mode="None">
                    <transport clientCredentialType="None" proxyCredentialType="None"
                        realm="" />
                    <message clientCredentialType="UserName" algorithmSuite="Default" />
                </security>
            </binding>
        </basicHttpBinding>
        <wsHttpBinding>
          <binding name="WsHttpBindingConfig">
            <security mode="TransportWithMessageCredential">
              <transport clientCredentialType="None" />
              <message clientCredentialType="UserName" />
            </security>
          </binding>
        </wsHttpBinding>
        <webHttpBinding>
          <binding name="webHttpBindingConfig">
            <security mode="None"/>
          </binding>
        </webHttpBinding>
    </bindings>

  <!-- to enable IIS authentication for WCF, we have to switch to compatibility mode -->
  <serviceHostingEnvironment aspNetCompatibilityEnabled="false"
    multipleSiteBindingsEnabled="true" />
  <services>
    <service name="WcfService"
             behaviorConfiguration="Behavior">
      <endpoint address=""
                binding="basicHttpBinding"
                bindingConfiguration="CustomBasicAuth"
                contract="IWcfService" />
    </service>
  </services>
</system.serviceModel>

我的接口定义是这样的：

<OperationContract()>
<WebInvoke(BodyStyle:=WebMessageBodyStyle.Bare, RequestFormat:=WebMessageFormat.Json, ResponseFormat:=WebMessageFormat.Json, Method:="GET")>
<WebGet(BodyStyle:=WebMessageBodyStyle.Bare, ResponseFormat:=ResponseFormat.Json)>
<ScriptMethod(UseHttpGet:=True, ResponseFormat:=ResponseFormat.Json)>
Function GetBills(ByVal userName As String, ByVal passwordHash As String) As List(Of Bill)

当我访问 URL 时

http://localhost:84/BillService.svc/GetBills?userName=demo&passwordHash=dummy

我得到一个空白页并且我的断点没有被触发

Answer 1

改变这个

<endpoint address=""
binding="basicHttpBinding"
bindingConfiguration="CustomBasicAuth"
contract="IWcfService" />

到

<endpoint address=""
binding="webHttpBinding"
bindingConfiguration="CustomBasicAuth"
contract="IWcfService" />

这可能有助于您使用 URL 访问您的服务

Answer 2

问题可能不在您的代码中，而在您的注释中。 WCF 可能会变得非常令人沮丧，因为您可以打开和关闭很多开关。首先添加一个

[ServiceBehavior(IncludeExceptionDetailInFaults = true)]

给你的服务实现。如果您仍然没有看到任何错误，您可以启用 WCF 跟踪： MSDN: Configuring WCF Tracing

对于 WCF 跟踪：

<configuration>
    <system.diagnostics>
        <sources>
             <source name="System.ServiceModel" 
                     switchValue="Information, ActivityTracing"
                     propagateActivity="true">
                  <listeners>
                       <add name="traceListener" 
                            type="System.Diagnostics.XmlWriterTraceListener" 
                            initializeData= "c:\log\Traces.svclog" />
                  </listeners>
             </source>
        </sources>
    </system.diagnostics>
</configuration>
